WILLIAM KUEHNE', OF AUSTIN, TEXAS.

VACUUM-OPERATED HAIR CLIPPER.

Application filed May 29,

To all whom it may concern:

Be it known that I, IVILLIAM E. lKUEHNE, acitizen of the United States, residing at Austin, in the county of Travis, 'State of Texas, have invented a new and useful Vacuum-Operated Hair Clipper, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a vacuum hair clipper and its object is to produce a hair clipper which is capable of being attached to any ordinary form of vacuum cleaner for the reclprocatlon of the cutting blade,

' the air passing into the vacuum cleaner acting to operate the blade and also to remove the hair as fast as it is out.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I- a'm aware that there may be modifications thereof.

- and Fig. 1 is a view of the complete apparatus as it appears ready for use. Fig. 2 is a vertical sectionalview of the cutting apparatus. I

Fig. 3 is a bottom plan view of the cutting apparatus,

Fig. 4 is a plan view of the lever and crank for reciprocating the cutting'blade,

Fig. 5 is a plan View of the top end of the cutter escape tube for carrying away the clipped hair, slightly-enlarged over Fig. 2.

The numeral 1 indicates the dust collecting chamber of any vacuum cleaning apparatus. This dust collecting chamber has a pressure below atmospheric contained therein, and has a pipe 2 which leads to a suitable bracket 3. This bracket is usually fastened to the ceiling or some other convenient height to allow the horizontally extending pipe to swing about the center of the bracket 3.

The pipe 4 in turn hasa flexible pipe 5 connected thereto WhlCl'l'iS connected to the tubular member 6 of the hair clipper. The pipe 5 is of such length as may be convenient to work over the head of a customer 1922. Serial no. 564,559.

sitting in the, barbers chair or at any convenient height.

The clipper consists of the tubular meniher 6 which has a handle 7 extending substantially at right angles to the tubular member 6, and. attached to the handle 7 is the bottom blade 8, screws 9, 10 and 11 securing the bottom blade to the clipper.

The bottom blade carries a bearing 12 for.

the pivot pin 13, and it carries a bearing 14 forthe lower end of the drive shaft 15. The drive shaft 15 is also journaled in a spider 17 at the upper end of the tube 6.

Inside the outer blade 8 there is a movable blade 18. This blade has lugs 19 and 20 thereon which supply the means for the re- I ciprocation of the blade 18.

The lever 21 is pivoted at its center on the pin 13, its rounded end 22 passing between the lugs 19 and 20, while at its opposite end it has two arms 23, 24 which engage a small roller 25 on the crank 26.

The shaft 15 has a pair of spiral vanes thereon as indicated at 27, '28, and when attached to the vacuum tube 5 the air passing will cause therotation of the shaft 15 and the reciprocation of the cutter. In this way as rapidly as the hair is clipped it is at once taken into the vacuum receiver 1.

What I claim is as" follows, but various modifications may be made in the construction shown in the drawings and above particularly described form, within the purview of my invention:
